Dr. Natasha Sharp recently joined the Burnett Lab as a postdoctoral researcher and will be further investigating the effects of low dissolved oxygen (hypoxia) and elevated carbon dioxide (hypercapnic hypoxia) on the immune defense of shrimp and blue crab. These animals frequently experience these conditions in the shallow coastal waters they inhabit. Originally from New Zealand, she moved to the USA to complete her doctorate under the guidance of Marius Brouwer at the Gulf Coast Research Laboratory, University of Southern Mississippi. Her dissertation assessed the effects of lipopolysaccharide (LPS) on blue crab (Callinectes sapidus) hemocytes. Her research focused on the changes in hemocyte number as well as cytological effects and differential gene expression.
